Surge in Long COVID Independent Medical Reviews Signals Cost Shift

August 11, 2025 | Sacramento, CA – MedLegalNews.com — Long COVID independent medical reviews are increasingly dominated by Long COVID claims, according to new data from the California Workers’ Compensation Institute (CWCI). Although these claims represent just 4.7% of COVID-related cases, they account for over 80% of medical treatment payments, underscoring a seismic shift in chronic illness cost allocation. This trend highlights how prolonged symptoms are reshaping medical dispute patterns and influencing long-term care standards in the state’s workers’ compensation system.

Key Findings from CWCI Analysis

  • From 2020 through 2022, nearly 126,400 insured COVID claims were evaluated by CWCI analysts. Only 14.6% received medical treatment, while 4.7%—approximately 6,000 claims—were Long COVID cases requiring extended care.
  • Long COVID cases accounted for 82.1% of the $128.4 million in medical treatment payments—highlighting their outsized financial impact. Total COVID-related payments reached $350.6 million, with Long COVID consuming 73.7% of all costs.
  • Average treatment costs on Long COVID claims were 105 times higher than non–Long COVID cases, and indemnity costs were 37 times higher, regardless of injury type.

Why It Matters to Legal and Compliance Professionals

COVID independent medical reviews tied to Long COVID disputes are now driving a disproportionate share of case activity in California’s workers’ compensation system, placing heavier demands on administrative processes and review workloads. These disputes not only prolong claim resolution but also introduce heightened financial exposure for employers and insurers due to extended treatment timelines and complex clinical documentation requirements.

For legal teams, the stakes are equally high. The evolving standards for diagnosing, managing, and disputing Long COVID cases—both within utilization review (UR) and IMR frameworks—are redefining litigation strategies. Attorneys must anticipate how shifts in medical evidence thresholds, compliance protocols, and procedural timelines will influence settlement negotiations, defense approaches, and potential precedent-setting decisions in the coming years.

Outlook: What Stakeholders Should Do Next

Stakeholders should prepare for a continued rise in COVID independent medical reviews related to Long COVID, underscoring the need for thorough medical documentation and evidence-based treatment protocols. Policy and risk managers should anticipate adjustments to insurance premiums as Long COVID reshapes the underlying cost drivers in workers’ compensation. Meanwhile, claims professionals are encouraged to follow CWCI updates and apply relevant research to guide claims handling, billing reviews, and legal defenses.
